KNOOKDOWN SHOW-CASE.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed. April 3, 1905. Serial No. 253,448.

To all whom it may concern.-

Be it known that I, RAYMOND MANOHA, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Knockdown Show-Cases, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates to knockdown showcases; and it consists in the novel construction of meeting-rails for adjoining sections, as hereinafter set forth.

The drawing represents a horizontal section through the meeting-rails.

A is one section of the knockdown case, and B an adjoining section, which, as shown, is arranged in a plane at right angles to that of the section'A. C and D, preferably, are the meeting-rails for these sections, which are of the following construction: The rail C is of greater thickness-that is, transverse to the plane of the section than width, while the rail D is of greater width than thickness relative to its own plane. Thus when the two rails are placed together their shorter dimensions will be combined to form a substantially rectangular cross-section which constitutes a corner-post of the case. .Each of these rails is grooved or rabbeted, as at a, to receive the glass panel E of the section, and the rail C is preferably fashioned on its inner portion to form a substantially triangular molding or filling strip in the corner between the panels of the two sections.

The rails C and D are secured to each other by providing one with a tongue I) and the other with a groove 0, which are adapted to engage with each other, and when thus engaged the sections are secured by screws F, which are arranged to enter the angling faces of the section C and to extend into engagement with the section D at an angle to the meeting plane of said sections. The effect of the construction when complete is that of a solid corner-post substantially square in crosssection, but having its inner corner beveled off. The securing-screws F are completely concealed from view from the outside of the casing and by reason of the angle at which they are arranged to the meeting plane of the rails the latter will be drawn together so as to tightly bind the tongue 6 in the groove 0. Thus a very rigid connection is formed between the two rails.

What I claim as my invention is- 1. A knockdown show-case comprising a pair of meeting-rails for the adjoining sections, which are arranged in planes substantially perpendicular to each other, each of said rails being rabbeted to receive the transparent panel from the outside, and said rails when placed together forming asubstantiall y square cross-section with the inner angle beveled off, and a securing-screw entering said beveled face and extending into engagement with the other rail at an oblique angle to the meeting plane.

2. A knockdown show-case comprising a pair of meeting-rails for adjoining sections, which are arranged in planes substantially perpendicular to each other, said rails having a longitudinally-extending tongue-and-groove engagement and each being rabbeted to receive the transparent panel frorn'the outside, one of said rails being of rectangular crosssection and the other being beveled at its inner corner, and the dimensions of said rails being such that together they form a substantiall y uniform distance between the glass panels and the outer face of the rail, and a securing-screw engaging the beveled face of one rail and extending into engagement with the other rail at an oblique angle to the meeting plane.

In testimony whereof I aflix my signature in presence of two witnesses.

RAYMOND MANCHA.
